The construction of the campanile and the dedications that took place between the groundbreaking in November of 1926 and the installation of the Fasoldt clock in May of 1927 were truly exciting for all those involved. The school spirit voiced by the students, faculty, and alumni during this time was immortalized into a visual symbol that stands today amidst an ever-growing educational institution. There have been several minor repairs done to the campanile over the years, one due to a lightning bolt that struck the clock tower in 1942 and another in 1990. The more important renovations, however, occurred in 1968, 1984, and 1995.

     The 1968 renovation of the campanile was confined to the carillon system within the structure. A few of the original fifteen chime bells had fallen out of tune, and the carillonneur at the time complained about the lack of versatility in the instrument. Following the Alumni Association's approval, the UNI Foundation arranged for the removal of four out-of-tune bells and the purchase of thirty-six new bells, which combined with those still in place to make a 47-bell carillon instrument. This project cost the newly-formed University of Northern Iowa $35,000, a little over half the original cost of the entire campanile. Another renovation of the carillon occurred in 1984, when a new keyboard and a central transmission system were added at the request of UNI's current carillonneur, Robert Byrnes. This project was also a result of age, this time on the mechanisms that ran the carillon rather than the bells themselves. Robert Byrnes stated to the Waterloo Courier at the time that he "must strike the wooden keys with a loosely clenched fist to make the bells ring." The renovation was handled by the I.T. Verdin Co. of Cincinnati, Ohio, which completed the $50,000 project during most of the summer of 1984. The 1968 and 1984 renovations were primarily maintenance and upgrading projects for the carillon housed within the campanile, keeping the musical instrument up-to-date and tuned. While the cost of these two projects together cost more than the campanile initially cost, the university and the students were more than willing to support the renovations for a structure that has represented the strong foundation of the university since its founding in 1876.

     The most recent renovation occurred in 1995. This project was centered primarily on the exterior appearance of the campanile, rather than within its functioning systems. During this renovation, the university raised funds to replace much of the exterior brick of the spire, to clean the granite blocks that make up the base of the structure, to modernize the heating and ventilation systems, and to add a large plaza surrounding the campanile. This major project modernized the area around the UNI campanile, making it a more comfortable place for students and faculty, especially during the campaniling tradition.
